<Snipped quote by LokiLeo789>
You mean a Holy Site made by multiple people? Yes, that is possible. It was discussed near the start, around the creation of the Celestial Citadel. It counts as two Holy Sites for rules purposes, but means you can pool more Might into it because you have multiple contributors.
P.S. The conversation starts here. The verdict on how joint Holy Sites tie into the rules are here and here. It was decided that the Celestial Citadel would not be a joint Holy Site, because in this instance it would be a major disadvantage four turns later not being able to make another Holy Site.
Essentially, each contributor receives half the total Might invested in the Joint Holy Site, but it counts as two Holy Sites for the purposes of counting your allowed number of Holy Sites, you must wait twice (?) as long before you build your next Holy Site, and you may only be part of one Joint Holy Site. There are no limits to the number of contributors.
Well that's definitely not worth the bang for your buck. That's a Nigerian Email Scheme in the flesh. Thankfully there are loopholes in which on can use to sort of bypass this mechanisms, similar to what was done with the Celestial Citadel. Thank you, oh Grand Perfectus Historious of Divinus.
